Etch 1.0.1-dev.9 (latest build of master)

The newest build of master, rebuilt on every merge. Unsigned, so
SmartScreen will warn; see the README.

Built from 4d7834038e5a9720fb42235cf75846a9f05642d8.

For a fixed, reproducible build, use a versioned release instead.

Etch 1.0.0

A fast Notepad replacement for Windows that detects what you paste and transforms it in place. No save dialog, no telemetry, fully offline.

Download

Etch-Setup.exe - one per-user installer carrying both x64 and arm64. No administrator rights, no UAC prompt. Windows 10 and 11.

Etch is unsigned, so SmartScreen warns on first run (More info, then Run anyway). If you would rather not, the source is right here and you can build it yourself.

What it does

• Nothing is ever unsaved. Everything auto-saves continuously and closing a tab is not destructive, so there is no save dialog to interrupt you.
• It knows your text. Paste a JWT and it says JWT; press Ctrl+Enter and it decodes in place. JSON, Base64, URL-encoding, hex, timestamps and more are detected automatically.
• Transforms that chain. 42 built-in transforms (format and minify JSON, Base64 encode and decode, JWT decode, case conversions, sort and dedupe lines, hashes, escaping and more) apply in the same buffer, so Base64 to JSON to sorted keys is three keystrokes.
• Command palette. Ctrl+Shift+P finds any transform by name; Ctrl+Enter applies the one Etch suggests for what you pasted.
• A real editor. Syntax highlighting and folding, find and replace, multiple tabs, and a light or dark theme that follows Windows.
• Private by default. No telemetry, no account, fully offline. Installs per-user under %LOCALAPPDATA%; everything it writes is under HKEY_CURRENT_USER.

Good to know

• Optionally make Etch the default for .txt, .json and .log, and add "Open with Etch" to the right-click menu. Both are reversible any time from Ctrl+,.
• Source-available licence: read, download, build and run freely, including at work.
